The specific embodiment
The described steel framework wooden model of present embodiment connects the two pawl anchor clamps of adjustable tooth wedge, as Fig. 1, Fig. 2, Fig. 7, shown in Figure 9, it is made up of band blade tooth bar 1, band pawl sliding sleeve 2 and tooth wedge 3, band blade tooth bar 1 is made of ratch and claw, ratch one end elbow is a claw, be provided with a slotted hole 11 in the middle of the ratch, this slotted hole one side is provided with row's helical teeth hole 12; Band pawl sliding sleeve 2 is made of sliding sleeve and claw, and sliding sleeve one termination is provided with and the identical claw of ratch claw structure external form, and ratch inserts in the vertical oblong aperture 22 of sliding sleeve, and two claws are symmetrical arranged in opposite directions during plug-in mounting; Be provided with oblong aperture 21 in the middle of the horizontal side of sliding sleeve, with corresponding overlapping behind slotted hole 11 plug-in mountings in the middle of the ratch; Tooth wedge 3 is provided with one group of vertical helical teeth 31 on the rectangular plate body of one side, in tooth wedge 3 vertical insertion sliding sleeves and the overlapping hole of ratch, and the vertical helical teeth 31 on the rectangular plate body of tooth wedge 3 these sides and helical teeth hole 12 corresponding the plugging together of ratch.
Band blade tooth bar 1, band pawl sliding sleeve 2 are fine steel casting with tooth wedge 3 in the present embodiment.Ratch appearance and size is (55 * 20) mm, and the vertical oblong aperture 22 of slide is of a size of (57 * 22) mm.Because be precision castings all, ratch can insert the vertical oblong aperture 22 of sliding sleeve smoothly.Moreover band helical teeth slotted hole 11 length are 165mm in the middle of the ratch, and tooth wedge 3 width are 25mm, and the difference of the two is 140mm, i.e. coarse adjustment size maximum can reach 140mm, can satisfy 100mm fully and with inner formword bar (design Breadth Maximum) coarse adjustment claw required distance is installed.The horizontal side of sliding sleeve oblong aperture 21 is of a size of (27 * 18) mm, and tooth wedge cross dimension is (25 * 16) mm, can satisfy the tooth wedge and insert in sliding sleeve and the overlapping hole of ratch.
The claw of described band blade tooth bar 1 is equipped with steel framework wood with the claw of being with pawl sliding sleeve 2 and touches the supporting internal orifice of frame external form 13,23, two internal orifice angles are 130～140 °, big angle at 45 of claw hook portion position and frame, identical with the special-purpose frame broken line back of the body of " R " type outer shape, be convenient to two-way chucking.Two internal orifice angles are 135 ° in the present embodiment
The claw of described band pawl sliding sleeve 2, the claw and the cross section of ratch own of band blade tooth bar 1 are " worker " font, promptly guarantee longitudinal rigidity, again weight reduction.In the present embodiment, as shown in Figure 5, the recessed 1mm of ratch B-B section middle pectoral plate; As shown in Figure 6, the recessed 5mm of ratch C-C section middle pectoral plate, as Fig. 3, shown in Figure 8, the also recessed 5mm of two claw section webs.
The claw of described band blade tooth bar 1 and ratch consubstantiality, the claw and the sliding sleeve consubstantiality of band pawl sliding sleeve 2 are one machine-shaping.
The helical teeth hole 12 of described band blade tooth bar is corresponding mutually with vertical helical teeth of tooth wedge 31, their orthogonal rake is 7～8.5 °, and from 8.53 ° of requirements of the locking angle, the self-locking of tooth wedge helical teeth can not become flexible less than the steel surface pressure, nature claw clamping force can not reduce yet, and realizes the purpose of permanent card pilled-in selvedge frame.Their orthogonal rake is 8 ° in the present embodiment.
Described tooth wedge 3 one ends are provided with hammering 32, are to use during with hand hammer hammering tooth wedge 3 upper ends.
Use principle is as follows: as shown in figure 14, when assembly unit steel framework wooden model band bar seam, these anchor clamps are installed near cross rib and frame infall, the coarse adjustment slide makes two claws block two " R " type frame outside, it is penetrating to adjust overlapping hole, insert the tooth wedge from top to bottom, the tooth wedge can insert sliding sleeve and the overlapping hole of ratch smoothly, corresponding the plugging together in helical teeth hole of vertical helical teeth of tooth wedge and ratch, suitable hammering tooth wedge down firmly is till motionless, like this, the tooth wedge promotes slide along the little slip of ratch, makes two claws further close, clamps two " R " type frame.And because helical teeth and helical teeth hole have the engagement self-locking action, slide can not become flexible, and the clamping action of two claws can not become flexible naturally yet, realizes permanent chucking purpose.
The claw internal orifice is identical with " R " type frame broken line back of the body outer shape, can have two-way function during the claw chucking, the one, vertical frame is greatly towards interior equivalent oppositely promotion, make two frames clip bar and be close to, the 2nd, big angle at 45 of claw hook portion position and frame is when claw tightens relatively, naturally has thrust to the frame back side, make two frames and together near the ratch medial surface, it is concordant to impel wood glue to close slab joint, plays two-way snap action.
